BEFRIGEBATING APPARATUS.

Application fled October 28, 1921. Serial No. 510,461.

To all 'whom t may concern.:

. v Be it known that I, HARRY W. WoLFE, a the pre-cooling coil 19-by a pipe 21, the other citizen of v.the United States, residing at- Philadelphia, in the countyof Philadelphla' and State of Pennsylvania, havevinvented certain new andl useful Improvements .in Refrigerating Apparatus, of which the following is a specification.

The present invention relates more articularly to apparatus for separatlng oi from the gas, condensing the ammonia gas, and providing means for pre-cooling the ammonia after it has passed through the refrlgerating member and prior to its introduction into the separator and condenser.

An em?A odiment of the invention is illustrated ir the accompanying drawings, wherein Z- Figure l is a diagrammatic view of a refrigerating system, showing the improved apparatus in place therein,

Figure 2 is a sectional view on an enlarged scale through the improved apparatus,

Figure 3 is a plan view of the same,

Figure 4 isan end elevation.

In the embodiment disclosed, an elongated and horizontally disposed ammoniareservoir 5, preferably cylindrical in form is carried by suitable supports 6, and rising from the central portion thereof, is a vertical cylin. drical tower 7 that opens at its lower end into the said reservoir. In the upper portion of this tower is a partition 8 forming a lowercondensin chamber 9 and an upper separating cham er 10. The partition supports an open ended stand pipe 11 that thus affords communication between the vupper end of the chamber 10 and the upper end of the chamber 9. A coil 12 for containing a coolin or condensing agent is located longitudina y in Athe chamber 9 and extends downwardly into the reservoir 5. The lower end 13 of this coil constitutes the intake and the upper-'end 14 the outlet therefor. Lo cated inthe lower portion of the reservoir 5 is a pre-cooling coil 15, and a liquid outlet. pipe 16, passing through the top of the reser voir 5, extends to alpoint close Ato the bottom thereof. l j l The preferred form-of system is outlined in Figure .1, the compressor being shown at 17, and having its discharge connected to a pipe 18 leading to the separating chamber 10 below the top of the stand pipe 11. A refrigerating coil or member is shown at 19, its

inlet being connected by a pipe 20 to the pipe 16, its outlet being connected to one -end of end of said pre-cooling'coil being connected by a pipe 22 to theintake of the compressor.

drawn from the reservoir 5 and passes through the refrigerating coil 19. It is then directed bythe pipe 21 through the precooling coil 15 where any'liquid contained willassist in cooling the ammonia in the reservoir 5. The gasthen passes through the compressor and lis delivered into the contact with the coil and becondensed into' liquid that, will find its way into the reser- --voir 5, and'thus 'be in condition "to be passed again through the system'.

From the foregoing, it is thought that the construction, operation and many advantages of the vherein described invention parent to those skilled in the art, without further description, and it will -be understood that various changes in the size, shape, proportion and minor details of construction, maybe resorted to without departing from the` spirit or sacrificing any of the advantan es of the invention. l

aving thus fully described' my invention, what I claim as new, and deslre to secure by Letters Patent, is; 1. In apparatus of the character set forth, the comblnation with a hollow base, offa condensing tower mounted thereon and having an open bottom Ain open communica- 6o In this system the liquid ammonia is withrchamber 10. Here any oil will be deposited,

tion with the upper portion of the base,

means for subjecting the tower to the ac-4 tion of a cooling medium, an oil separating chamber, and a stand pipe vconnecting the upper portion of the separating chamber vloo with theV upper portion of the condensing j tower.

2. In apparatus of the character set forth, the combmation with a condensing tower having a condensing chamber and a .sepa-- rator chamberabove the condensing Achamber, a standpipe affording Vcommunication Y an extended hollow base loisv forming a liquid reservoir that communi. Gates with the lower end of the condenser chamber, and a cooling coil located in the condensing chamber.

3. In apparatus of the character set forth, the combination kwith a substantially horizontal tubular liquid reservoir, of a Vertical tubular tower supported therein and in communication therewith, a transverse partition in the upper portion of the tower, forming an upper separating chamber and a Alower condensing chamber, a standpipe affording communication between the upper portions of the chambers, and a condensing coil located in the condensing chamber and extending into the liquid reservoir.

4. In apparatus of the character set forth, the combination with a hollow base constituting a liquid reservoir, of a condensing tower mounted on the base and having an open ,lower end communicating therewith,

and means for holding a cooling medium lo=Ivy cated in the tower and extending through the lower open end in to the reservoir.

5. n apparatus of the character set forth, the combination with a hollow base constituting a liquid reservoir, of a condensing Maase@ tion betweenits upper end:v and the upperl end of the condensing tower.v f

6. In apparatus 'of the character set forth, the combination with anelongated tubular base constituting a liquid reservoir, of a condensing tower upstanding from an intermediate portion of the base and having an open lower end in communication therewith, means in the tower and extending into the reservoir for passing a cooling liquid therethrough, an oil separator chamber having communication between its upper portion and the upper portionoi` the zcondensing tower, and a pre-cooler located in the lower portion of the liquid reservoir-a Y ln testimony whereof, lzaiiix'my signature in the presence of two witnesses.
